Quorum UNITED STATES PATENT OFFICE,

OIL-HEATER.

Application filed February 5, 1917.

T 0 all whom it may concern:

Be it known that I, STEPHEN B. MoRss, a citizen of the United States, and resident of Rahway, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Oil-Heaters, of which the following is a specification.

My invention relates to improvements in heaters commonly called oil heaters and oil stoves and has particular reference to such heaters provided with means for the produotion'of a blue flame, as of the Bunsen burner type, from kerosene oil.

One of the objects of my invention is to provide means whereby the wick may be readily lighted and the blue flame will be quickly generated, whereby to avoid the production of objectionable odors from burning oil, and whereby, also, the parts of the burner are readily rendered accessible for cleaning and removal of the oil font for filling.

Another object of my invention is to provide such a heater having increased heating efliciency, and generally to simplify and make efficient heaters of the class referred to.

Reference is to be had to the acoompanyin drawings forming part hereof, wherein,

Figure 1 is a central sectional view, partly in elevation, of an oil heater embodying my invention;

Fig. 2 is a section on the line 2-2, in Fig. 1;

Fig. 3 is an enlarged detail plan view;

Fig. 4 is a section on the line 4-4, in. Fig. 3, and

Fig. 5 is a detail of the top of the heater.

The numeral 1 indicates a hollow base of any suitable construction shown provided with an air inlet opening 2, and at 3 is an oil font adapted to fit in said base and shown provided with a bail 3 and with a central draft tube or passage 4 registering with opening 2 for the passage of air to the burner. At 5, 6, are inner and outer spaced tubes of the burner adapted to receive the wick 7 therebetween in any well-known manner, an operating rod 8 being adapted to raise and lower the wick as may be desired. At 9 is a cylinder or combustion chamber removably fitted over the burner, to act in the nature of a flue or chimney for products of combustion as well as a heating drum or cylinder. The combustion chamber or cylinder 9 is removably fitted over the burner and a portion of the generating chamber of Specification of Letters Patent.

Serial No. 146,585.

the burner is connected with said combustion chamber or cylinder to be removed therewith from the burner, and to be restored therewith to position on the burner. F or such purpose I have shown a cap in the form of a plate or disk 10 having an opening 11 and located at the lower part of the combustion chamber or cylinder 9, said cap 10 forming the top portion of the casing of generating chamber 12. Said chamber is provided with a cylindrical wall 18 having perforations 14, which wall surrounds the tubes and wick and is suitably spaced therefrom, said cap 10 overlying the wall 13. Cap 10 is shown provided with a depending annular web or flange 15 cooperating with wall 13 to inclose the corresponding portion of generating chamber 12. The gases from the generating chamber 12 flow through the opening 11 in the cap or disk 10. The wall 13 may rest upon the top wall 16 of font 3 (Fig. 4). A perforated air distributor 17 fits within the inner wick tube 5 and may removably rest upon a shoulder 18therein, the narrow neck portion 18 of said distributer being shown centrally disposed within opening 11 of cap 10. Said distributer is shown provided with a plate or disk 19 at its upper end extending above cap 10 and providing a space for the escape of gases and flame from the generating chamber above the wick. By the means described the combustion chamber or cylinder 9 may be raised from the base and will carry the cap or disk 10 with it, which gives ready access to the wick for lighting it, whereby, also, the air distributer and the perforated wall 14 may be removed and all parts may be readily cleaned. When the combustion chamber and cap 10 are removed from the wick and the latter is lighted, the flame will quickly spread around the wick as it is then I tened on the base.

wick may be almost instantly adjusted to the desired position for production of blue flame of the desired volume. The combustion chamber or cylinder 9 serves in the nature of a draft chimney for the production of a suitable draft for the burning flame causing very rapid flow of the gases formed within the generating chamber to the burning mixture (within and without the generating chamber) the result of perfect combustion of the gases producing an intense flame without the generating chamber, suitable for heating or cooking purposes.

As a convenient means for adj ustably supporting the combustion chamber or cylinder 9 and the cap or disk 10, with respect to the burner, I have shown the cap pivotally connected with the base 1, by hinging means at 20, whereby the combustion chamber and cap may be tilted to permit access to the burner. A suitable catch 21 on the base may coact with an opening 22 in the outer portion of cap 10 for retaining the latter fas- Cap 10 and extended portion 10 thereof may be made in a single piece of material or in several pieces fastened together. I have shown the cap provided with an annular shoulder 23 receiving and centering the combustion chamber or cylinder 9.

The combustion chamber may be secured upon cap 10 by any suitable means. The base 1 is shown provided with openings 1 to admit air to the perforations 14 in wall 13 to direct air through said perforations into the generating chamber for the production of a blue flame by commingling with gases generated from the oil by the heat of the parts contiguous to said chamber, the air being directed to the perforations 14 below the extended portion of cap 10, the air for the distributer 17 flowing through the central draft passage 4 and opening 2 in the base, the products of combustion flowing into chamber 10.

I have shown a drum or cylinder 25 surrounding and spaced from combustion chamber 9, providing therebetween a flue 26 for the passage of air to be heated, the cylinder or drum 25 being shown provided with openings 27 near its base for the admission of air to said flue. At 28 is a plate shown fitted within cylinder or drum 25 and resting upon the combustion chamber or cylinder 9, a depending shoulder 29 on said plate serving to center said combustion chamber. Said plate has an opening 30 in register with the combustion chamber for the passage of products of combustion. The cover 31 is shown upon cylinder or drum 25, and bolts 32, depending from said cover through openings 33 in cap or plate 10 and there secured by nuts, serving to retain the parts 9, 25, 28 and 31 securely together, whereby all said parts will be tilted as a unit when swung on hinge 20. Cover 31 is shown provided with openings 34 adapted to be covered and uncovered by a valve or disk 35 having openings 36 to register with the openings 34, said valve or disk being pivotally supported at 37 on cover 31. \Vithin cylinder or drum 25 and between covers 28 and 31, is a chamber 38 in which the heated products of combustion rising from combustion chamber or cylinder 9 commingle with the air flowing through chamber 26, the heat from combustion chamber 9 radiating to the air in chamber 26 serving to initially heat the same, and such heated air will be further heated by commingling with the products of combustion in chamber 38, whence such highly heated air may flow through the openings 34 and 36 in accordance with the adjustment of valve or plate 35. The outer wall of chamber 38 is shown provided with perforations 39, and cooperative with said perforations is a perforated valve or ring 40 shown rotatively supported within and against the wall of chamber 38. Valve 40 is shown provided with a handle 41 projecting through one of the openings 39. When the apertures 40 of valve 40 register with the apertures 39 of chamber 38 the heated air in said chamber may flow through said apertures, and then the apertures 34 of cover 31 may be closed or opened by valve 35 as desired. lVhen, however, it is desired to direct all the heated air through the apertures 34, as for cooking or boiling water upon the heater, the valve 35 may be adjusted to cause its openings 36 to register with the openings 34 and valve 40 may be adjusted to close openings 39 to permit heated air from chamber 38 to escape through said openings 34.

By the means described I am enabled to provide a combustion chamber 9 of such dimensions as to act in the nature of a chimney for 'the burner, to induce a draft through the latter, while at the same time heating the air in the surrounding space 26. This arrangement aifords the advantage of delivering heated air from the heater or stove without requiring such air to flow through the cylinder or drum that incloses the products of combustion, since I find it advantageous and conducive to the production of a more intense flame and better combustion of the gases to exclude outside air from the combustion chamber rather than to admit air thereto, which has a tendency to produce white tails on the blue flame, although it will be understood that a moderate amount of air can be admitted to combustion chamber 9 without rendering my improvements wholly inefficient. The heated air rising in the combustion chamber 9 and the heated air rising in the chamber 26 commingle and are additionally heated through expansion in chamber 38, before passing therefrom to the outer air.

Having now described my invention what I claim is 1. In a heater the combination of a base provided with openings, a font having a burner, a combustion chamber registering with the burner, a drum surrounding. and spaced from the combustion chamber, means to admit air to said space, a plate over the base supporting the combustion chamber and drum, a cover having an opening registering with the combustion chamber and extending to the drum and provided with openings, a cover over the drum spaced from the first named cover providing an air mingling and heat expanding chamber, and means securing said covers to the combustion chamber and drum upon said plate.

2. In a heater the combination of a base, a burner supported thereby, a combustion chamber registering with the burner, a drum surrounding and spaced from the combustion chamber, means to admit air to such space, a cover having an opening registering with the combustion chamber and extending to the drum and provided with openings, a cover on the drum providing an air mingling and heat expanding chamber between the cover and said plate, the side walls of said chamber having openings, and an apertured valve cooperating with said wall at said openings, and means to adjust said valve.

Signed at New York city, in the county of New York, and State of New York, this 3rd day of February, A. D. 1917.
